WINDOW.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed October 24, 1910. Serial No. 588,753.

To all whom it may concern:

Be it known that I, EDsoN POTTER, a c1t1- zen of the United States, residing at Brighton, in the county of Monroe and State of New York, have invented a new and useful lVindow, of which the following is a speclflcation. I

The invention relates to improvements 1n windows.

The object of the present invention is to improve the construction ofthat type of windows, equipped with vertically slidable stiles and horizontally pivoted sashes, andto provide a simple, strong and efiicient device adapted to be readily applied to an ordlnary window to convert the same into a reverslble window.

\Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is an elevation, partly in section of a window constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is an enlarged perspective view of a portion of one of the slidable stiles or bars and its casing. Fig. 4 is an enlarged detail sectional view, illustrating the arrangement of the sash when the same is reversed. Fig. 5 is a horizontal sectional view on the line 55 of Fig. 1. Fig. 6 is a horizontal sectional view on the line 6-6 of Fig. 1. Fig. 7 is a detail vertical sectional view, illustrating the manner of pivoting the sash to the slidable bars or stiles.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 and 2 designate upper and lower window sashes, each centrally pivoted at opposite sides by a horizontal screw 3 to a vertically slidable stile or bar 4, mounted in the usual vertical groove or guide-way of the window frame or casing 5, and equipped with a sheet metal casing 6. The sheet metal casing 6 is constructed of a single piece of aluminum, or other suitable sheet metal, and

it consists of an inner wall 7 and opposite side walls 8 and 9, provided with inwardly extending longitudinal flanges 10, embracing the rear face of the slidable stile or bar 4. The longitudinal flanges 10, which are set at an angle, converge inwardly and are arranged in longitudinal grooves 7 in the rear face of the slidable stile or bar 4. The grooves taper inwardly and present outer angularly disposed faces or walls to fit the longitudinal flanges 10 and inner parallel shoulders or walls against which the inner edges of the longitudinal flanges abut. By

this construction the longitudinal flanges are efl ect-ually prevented from springing outwardly and becoming disengaged from the slidable stile or bar. The stile or bar 4 is arranged within the casing, and the inner wall 7 fits againstthe inner or front face of the said stile or bar and the adjacent side edge of the frame of the sash. The side walls 8 and 9 and the inwardly extending flanges 10 fit the walls of the groove or guideway of the window frame or casing, and protect the slidable bar 4 from wear and enable the same to slide freely in the guideway of the window frame or casing.

The slidable bar 4 is provided in its rear face with the usual sash cord receiving groove 11 to enable a sashweight of the ordinary construction to be applied in the usual manner to the slidable bar. Any other kind of balancing means, however, may be employed and the construction is also applicable to any kind of sliding sash whether balanced or not equipped with counter-balancmg means. The pivot screw 3 extends through a central opening 12 of the metallic casing, which has its side walls 8 and 9 split at 13 at points below and above the plane of the central'opening 12. The shorter portions of the side walls 8 and 9 are provided with longitudinal side flanges 14, arranged at right angles to the plane of the inner wall 7 and forming stops for engaging the pivoted sash. Each longitudinal flange 14 is formed by bending the sheet metal at right angles to the inner wall, and then backwardly on itself in the plane of the side walls. By constructingthe metallic casing in this manner, it may be stamped, or otherwise formed from a single piece of sheet metal, and it does not require screws or any similar fastening devices for securing it to the slidable bar. The side walls and the inwardly extending flanges 10 are adapted to firmly embrace the slidable bar, and the pivot screw will retain the metallic casing and the slidable bar against relative longitudinal movement. The slidable device composed of the bar and metallic casing is adapted to be applied to an ordinary window by cutting oif a portion of the sides of the frames of the sashes and pivoting the slidable members to the sides of the said frames. The sashes are adapted to be raised and lowered in the usual manner and may also be swung on their central pivots to reverse-them to expose their outer faces for cleaning or any other purpose. The sashes are locked in a vertical position by means of a suitable spring actuated bolt 15, mounted on each of the sashes and engaging a socket 16 of the slidable member. Any suitable fastening means may be employed for this purpose.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with a sash, and a slidable bar pivoted to the side of the sash, of a metallic casing receiving and frictionally engaging the slidable bar and constructed of sheet metal and consisting of an inner wall, and side walls having inwardly eX- tending longitudinal flanges embracing the rear faces of the slidable bar, said side walls being split above and below the center of the slidable bar and provided above and below the plane of the pivot of the said bar with integral longitudinal side flanges arranged to limit the swing of the sash and formedby bending the sheet metal at right angles to the plane of the inner wall of the metallic casing and backward on itself in the plane of the side walls.

2. The combination with a sash, of a slidable bar pivoted to the side of the sash and provided in its rear face with spaced longitudinal grooves tapered inwardly and forming outer angularly arranged walls or faces and inner parallel shoulders or walls, and a metallic casing receiving and engaging the slidable bar and constructed of sheet metal and consisting of an inner wall, side walls and spaced'inwardly extending converging longitudinal flanges extending into the grooves at the inner faces of the slidable bar and fitting the angularly disposed faces or walls of the said grooves and engaging the shoulders thereof, whereby they are interlocked with the slidable bar, said side walls being split above and below the center of the slidable bar and provided above and below the plane of the pivot with integral longitudinal side flanges arranged to limit the swing of the sash and formed by bending the sheet metal at right angles to the plane of the inner wall of the metallic casing.

In testimony that I claim the foregoing as my own, I have hereto aliixed my signature in the presence of two witnesses.

EDSON POTTER.
